I understand that this is not the design of choice now.

they also had problems shocking the drive-train when a shift happens.

Makes sense. With some mechanism internal to the output shaft that forces pawls out to engage (at least judging by the drawing), the changeover would be anything but smooth at full throttle. That is the positive characteristic of any clutch based system (with or without temporarily decreasing throttle) - lets there be transition from 0 to full torque over a more reasonable interval. Second suddenly engaging the pawls must take a significant toll on those components over the life of the transimission.
